while building my 5.45x39 upper, I realized that the YHM Gas Block I ordered didn't come with a roll pin. I am temporarily using a cut-down cotter pin. I figured since this kit came with 12 different roll pins, I would pick it up and be set for roll pins for a while. It turns out that none are the correct size and my excitement was killed. The roll pin I need for my gas block is between 3/32" and 1/8".
What size am I looking for? |
